So far so goodBy japickaon 1/31/2015

I have this in a phosban 150 reactor along with the BRS lignite carbon, I am about a week in and once I got the flow right through the reactor I can tell an immediate difference. I was using seachem sea gel and it worked ok, but this combination works SOOO much better. Nuisance algae has been all but stopped. I used to have to scrape the tank sides about once a week, once I got this stuff up and running I can tell the growth on the glass has slowed WAY down. Phosphates were always pretty low in my tank, but this stuff has it basically at 0, or just above. I have not been running it long enough to probably get it all the way down yet. I not looking back I am going to run this stuff from now on.

a mustBy Christopheron 12/24/2014

This works wonders if you follow the instructions. I've been running it for close to a year now, and it is a staple for sure. You must use the correct amounts, and you must change it out. Don't expect results if you are to frugal with it.

Been using a cup of this in my reactor for about two weeks and i can already see a difference in my tank. Algae is almost gone. Phosphates are virtually at 0 now. I will continue using this product as long as I have an aquarium.

I've been using this in a filter sock in my hob filter. Although not the most efficient use of GFO it still does a great job of keeping my phosphates low. I only wish I had a larger setup so I could use a media reactor.

Good stuff, a bit dustyBy Ryanon 12/10/2014

Just make sure you rinse it well before placing it in the system obviously. It does contain a fair amount of dust, but does the job once installed. No complaints here, you get a lot for what you pay for.

for the priceBy justynon 12/4/2014

A great product for the price. I run gfo a long side my carbon and changing this product out gets expensive, once I found out about BRS I was hooked with them.

Excellent gfo for the price. By Rogeron 12/3/2014

Using this gfo has greatly helped me keep my p04 levels down to a minimum. Compaired to the expensive other brands it's crazy not to buy this stuff.

Increasing the frequency off my GFO changes has decreased the speed at which my Hair Algae problem has returned. I will keep this frequency pace to hopefully completely eliminate the algae problem all together.

I run a 37 gallon heavily stocked with fish and LPS corals. This stuff removes phosphates FAST! Just make sure you use a reactor and don't just put it in a media bag you will never get the same results just running it in a media bag in a external filter. Keeps my reef looking pristine!

I think it's a very reasonably priced media, I'm happy.

This is my second batch of GFO Granular Ferric Oxide from BRS. Fantastic results in removing Phosphates. Would recommend it to anyone wanting a good GFO product

This stuff is the best I've been using it for two weeks and the phosphates are down to near 0 I'll never run a tank without this and they're dual reactor !!! Once again an excellent product by Brs

If you aren't burning through two cups of GFO every one to two weeks, then this is a great product, bang-for-buck wise!

...never though I would pay so much for a jug of pulverized rust. Maybe I shouldn't have sold that old car... Could have scraped it right off the bumper. LOL! Seriously though... It's good stuff and a decent price when compared to other products.

Been using this GFO for over a year and it's good stuff. Keeps my phosphates in check with no problems. Lasts a decent amount of time before I have to change. A little bit of dust to wash out before starting a new batch. No issues with it breaking down as long as you keep the water flow moderate. Works great for me. Thanks BRS

Best GFO for the cost!By Davidon 10/2/2014

I tried several other products that claimed to clear up phosphate issues but none of them compared to the amazing results I have seen using BRS GFO. It is of the highest quality and the results show it!. The only GFO I will run through my reactor!

I used this mixed with small particle carbon in my reactor, and works perfectly.

works like all the other anti phosphate products at what seems like a quarter of the price.

Rinse it first By Davidon 7/30/2014

I did my homework when it came to adding chemical media in my reef. I have no complaints with this GFO. My Phosphates levels are always nearly undetectable and no algea, just make sure you rinse well before use.

Performs well - But needs to be rinsed Very WellBy Alexon 7/19/2014

Alex would recommend this product to a friend

We used the High Capacity GFO first and it worked great. This time we decided that since we had a large reactor and plenty of space, we could use the GFO that wasn't as compacted to be a little cheaper . It worked for its primary purpose - get the phosphate out. It's just that we had to rinse it with several gallons (5-10) of water to get the dust out and it still left orange dust on the bottom of my sump. I think we will go back to the high capacity stuff after we go through this batch.

This has been a great asset to my water treatment system removing phosphate due to my overfeeding my tank
